CONCRETE-MIXER.

Application filed December 27, 1910.

To all Lc/tom it may concern:

Be it known that I, SAMUEL FINLEY, a citizen of the United States, residing at Geneseo, in the county of Livingston and State of New York, have invented certain new and useful Improvements in Concrete- Mixers, of which the following is a specification.

The object of this invention is to provide an improved concrete mixer that will mix the various elements of concrete in predetermined proportions continuously feeding regularly to the machine continuously at the proper rate each of the elements that is to be mixed into the concrete, giving as its product a concrete of uniform texture.

A further object of my invention is to first mix the various elements of the concrete dry, and after the dry mixing is iinished to add thereto the water in proper proportion and thoroughly mix the water with the solid ingredients of the concrete, discharging the wet concrete thoroughly mixed in all parts from the machine.

My invention also consists of various details of construction that will be fully pointed out in the specification and claimed in the claims.

In the accompanying drawings illustrating my invention, Figure l is a side elevation of my finished concrete mixer, certain parts being shown in dotted lines. Fig. 2 is a top plan view of the saine. Fig. 3 is a section on the line 23a-3@ of Fig. 1, looking in the direction of the arrow. Fig. 4 is a front elevation of the machine. Fig. 5 is a detail sectional view of a portion of the feeding drum, showing the paddles mounted therein. Fig. 6 is a side elevation of one of the paddles, showing it mounted on a section of the shell of the mixing drum. Fig. 7 is a perspective view of the rear end of the machine showing the elevating drums and hopper. Fig. 8 is a vertical transverse section through a part of one of the elevating drums. Fig. 9 is a vertical longitudinal section through a part of one of the elevating drums, the section being taken on the line 9X-9X of Fig. 8.

machine, supported at its front end by the bolster 2, which in turn is mounted on the axle 3, which axle is in turn supported by the wheels 4, il, the axle 3 being provided with a fifth wheel to turn under the bolster 2 1n the usual manner as ordinarily provided in wagon construction. The rear end of the frame is supported by the bolster 6 which in turn is mounted on the stationary axle 7, which in turn is supported on wheels 8, 8.

The framework 1 of the wagon is composed of two channel irons 9, 9 which run the full length of the wagon frame and are spaced apart at suitable intervals by the cross bars l0 interposed therebetween. Interposed between the framework 1 of the wagon and the front bolster 2 are wooden cross bars 11. On top of the framework l are the cross bars 12, forming a platform. Mounted on the framework of the wagon are the nedestals 18, 13 at the top of which are provided suitable bearings 1st, in which is mounted the shaft 15. On this shaft 15 are mounted the sprocket wheels 16, 16a. On this shaft is also mounted the beveled gear 17, which gear meshes with the beveled pinion 18 mounted on a suitable shaft, which shaft is supported in the bearings 19, 19. At its rear end this shaft carries a sprocket wheel 29, and between the bearings 19, 19 it carries the sprocket wheel 21. The shaft 15 may also be provided with a suitable sprocket wheel keyed thereon, driven by a chain, which in turn may be driven by an engine mounted upon the front platform 12, the sprocket wheel, driving chain and engine being omitted from the drawings as they constitute no necessary part of my invention.

The sprocket wheel 21 has a chain 22 thereon which meshes with the sprocket wheel 23 carried on the shaft 24. This shaft extends rearwardly from said sprocket wheel, being mounted on suitable bearings supported by the frame, and at its rear end carries the pinion 25 which meshes with the gear 2G which is fastened to the revolving drum 27. Driven by the sprocket wheels 16, 16a are the chains 28 which engage with sprocket wheels 29 and 30. The sprocket wheel 29 is keyed to the drum 81 and the sprocket wheel 30. is keyed to the drum 32.

If the sprocket wheels 16 and 16a are of the however it is desirable to make the drums 3l and 32 revolve with different angular velocities, and this result is secured by varying the size of the sprocket wheels 16 and 16a. If it is desired to mix concrete with simply lcement and gravel, the drums 31 and 32,

which may be called feeding drums, will be revolved at the same angular velocity. The drums 3l and 32 can both be used to feed the material, and in such case they may be revolved at the same angular velocity. ln such case however if desired only one of the drums maybe used and the other may be permitted to run idly, or may be stopped from operating altogether.. 1f however it is desired to mix concrete with cement, sand, and crushed stone, then it will sometimes be necessary to revolve the drums 3l and 32 at different angular velocities. For example, a frequent mixture is one part of cement, two parts of sand and five parts of stone. The drum 31 4may feed the sand and the drum 32 may feed the crushed stone, and as two and one-half times as much crushed stone is used in the mixture as sand, it is desirable to make the drum 32 which feeds the stone feed two and one-half times as fast as the drum 31 which feeds the sand, and this measure is secured by making the drum 32 revolve two and onehalf times as rapidly as the drum 31. By varying the size of the sprocket wheels 16 and 16 the desired angular velocity of the drums 3l and 32 may be secured.

While I have mentioned a mixture of one, two and five, it will be understood of course that the machine may in the same way be adjusted l for any other mixture, Whether richer'or coarser than that above suggested, it being possible to vary the proportions to any desired extent.

rlhe drums 3l and 32 are mounted to rotate on the shaft 33, said shaft being free to rotate independent of the drums, the drums being idly mounted thereon. This shaft is supported in a bearing 3% carried in the upper part of the pedestal 35 which rests on the frame of the machine. The

feeding drums 3l and 32 are constructed as follows: A hub 36 is provided on which are mounted radially spokes 37, 37. While four of these are shown, it will be understood that they may be of any desired num ber, it being desired to leave as much opening between the spokes as possible in order to permit the easy shoveling of material into the vfeeding drum from the side. For this reason the number of spokes should be as few as'possible.

On the outer end of the spokes 37 and integral therewith is the periphery of the wheel 38. As shown in cross section in Fig: 3, the spokes are deep at the hub, tapering toward the periphery of the wheel, making 1n this way the spokes as strong as possible without increasing their thickness.4

The periphery of the wheel is provided with a flange 39 projecting inwardly, which iange normally projects over the chute l0 for the purpose of fending the material of the feeding drum into the said chute.

rifhe outer shell or periphery Lil of the feeding drum is riveted to the periphery of the wheel or fastened thereon in any suitable manner. This shell is made preferably of metal sheets bent to the desired shape and riveted together, and consists of a periphery with a deepy flange on each side thereof. By means of the flange on one side of the shell al, the shell can be riveted or otherwise suitably fastened to the periphery or rim of the wheel 38. lnside of the shell t1 are provided partition plates form ing between them pockets, by which the material is positively held and carried up on the revolution of the feeding drum, so that the material will be carriedthereby nearly to the top of the shell, at which point it will drop off ofthe partition plates or out of the pockets into the chute d0. The partition plates 42 will be set somewhat out of horizontal, being highest at the outside of the feeding drum on the side of the drum that is lifting, the tendency being to work the material toward the inside of the drum andaway from the flange 39, so as to the more positively feed it into the feeding chute et@ as the feeding drum rotates. The partition plates 42 areal-so set tangentially instead of radially in the shell al, as indicated by the dotted lines in Fig. l, it being evident that the partition plates will hold 3 the material and discharge it at a higher point into the feeding chute than would be the case if the partition plates were set radially in the shell. Each of the feeding drums 3l and 32 is provided with a chute l 40, which chutes converge toward each other so as to feed the material into the mixing drum, the slope of the chute being .such that the material will work by gravity into the mixing drum as it drops from the feeding I drums. The chutes ii0 are joined together at their lower ends.

Mounted at the top of the machine and supported from the frame in any suitable manner, is the cement hopper 43, in the i lower end of which is provided the feed worm la mounted on the shaft d5, which shaft at its forward end carries the sprocket' wheels a6. The sprocket chain 47 connects the sprocket wheels 46 with the sprocket wheel 20 above described, by which 4are joined together. As the chutes 40,40

aresteeply inclined, the various elements that are fed therein slidedown readily into the mixing drum 27. As heretofore described, this mixing drumy revolves continuously and by its revolving the material yfed therein is carried up and turned over and over, causing an intimate mixture of the various elements that are fed thereinto. y

lThe speed with which the shaft l5 of the cement hoppei` is rotated may be varied by changing the sprocket wheels a6 and 2O so that any angular velocity of the worm can be obtained, thus increasing or diminishing the feed of the cement, it being understood that any mixture that is desired is obtained by adjusting the angular velocity of the worm which controls the feed of the cement and the angular velocity of the feeding drums which control the feeding of the other ingredients of the concrete.

As shown in Fig. 5, the mixing drum is provided with paddles 47, which paddles consist of a blade i8 and a reduced shank a9, having a stud projecting therefrom which extends through the shell of the mixing drum 27 and is fastened in place thereon by the nut 50. These paddles may be fastened in any position on the drum but l prefer to place them diagonally therein as illustra-ted in Fig. 5, so as to cause the material to feed toward the discharge end of the drum as the drum is being rotated. By increasing the diagonal pitch of the blades 48 of the paddles, the material will pass through the drum faster and by decreasing the diagonal pitch of the blades the material will pass through the drum more slowly, in which case a more intimate mixture of the material will be secured.

l have found by experiment that in a drum two feet in diameter and four feet in length, with live rows of paddles placed therein with a one-third pitch, the material will be turned over often enough to mix it to the same extent that it would be mixed if turned twenty-four times with a shovel.

l form the paddles of the shape illustrated in Fig. 6 for the following reasons: rllhe interval between the blade of the paddle and the drum permits some of the concrete to pass between the paddle and the drum, which scours out the drum and keeps it clean, and prevents the accumulation of material at the corners which would tend to clog the drum up. The fact that some of the concrete goes under the paddle and other parts of the concrete go over the paddle increases the stirring action on the concrete and secures a more ed'ective mixture than would be possible if the blade of the paddle were set down immediately in contact with the drum.

Mounted on the frame is the water pipe 51 adapted to be connected to any suitable source of water supply, at the lower end of which l provide a cock 52 for letting in and shutting 01T the water. The flow of water may also be regulated by a gate valve, not shown. Y

\ As illustrated in Fig. l, the pipe extends forward and then up and then rearward. rihe end of the pipe is then fitted with an elbow from which rises a nipple,on which in turn is mounted another elbow, to which elbow is attached a sprayer. This sprayer is preferably placed over the rear end of the mixing drum, it being the object of my invention to mix the concrete thoroughly dry inthe forward part of the drum before it comes into contact with the water, and then mix it thoroughly with the water, after which it is discharged into a conveyer or into wheel barrows.

By forming the upper part of the water pipe as shown and described, l am enabled to control the flow of water more effectively, so asto secure an even supply of it at all times. It will be apparent from an inspection of Fig. l that when the cock 52 is closed, only so much water will run out of the pipe as is contained in the sprinkler, the balance of it being held in the pipe by the elbows and nipple. lllhis is true whether the machine sets on a level street or sets on a hillside, which would not be the case if the elbows and nipple were omitted. lf the water that is contained in the upper portion of the pipe could be run out when the machine is stopped, it is obvious that the concrete then in the machine would receive tool much water, and when the machine is started again this much of the pipe must fill again before the fresh concrete would receive any water. ln consequence the last of the concrete in the machine when it was stopped would receive too much water and the first of the concrete out of the machine when the machine is started again would be too dry. By arranging the pipe in the inanner aforesaid the concrete will be evenly moistened throughout. After the material has been thoroughly mixed in the mixing drum, it is discharged either directly therefrom into a wheel barrow or, as I have illustrated in the drawings, to a conveyer GO which l am now about to describe.

Bolted to the frame at the rear of the machine are the brackets 61, 6l on which is pivoted a trough 62. il plate 63 is riveted to the forward end of the conveyer chute, having depending therefrom a pin 64. A socket 65 is provided in the bracket 61 having an opening therein for said pin, in which socket said pin is carried and in which it is free to oscillate with the conveyer trough. A cotter pin 66 is provided in said pin for the purpose of holding it in place. ln this way the conveyer trough is mounted to oscillate through a considerable are of a circle.

They conveyor trough may be of any desired length, up to a maximum of about- 73 mounted on the frame 7 0. lts forward Y end is pivoted on the crank pin 7 4C which is mounted on the crank 7 5, which in turn is mounted on the lower end of the shaft 68. This shaft is divided, and between the upper and lower portion thereof is interposed the two portions of a clutch 7 6 and 77. The lower portion of the clutch 77 is keyed to its shaft and the upper portion of the clutch 7 6 is feathered on its shaft, on which it is free to be raised and lowered by means of theJ lever 7 S pivoted on the frame of the machine at 79. By raising the clutch member `76 the conveyer may be thrown out of action, and by lowering it the conveyer may be thrown into action again. The shaft 68 is supported above by the bearing 69 and below by the bearing 80. rlhe shaft GS'carries at its upper end a beveled gear 81 which meshes with a pinion 82 mounted on the shaft 83, which shaft is mounted to rotate in the sleeve Se and is driven at its forward end by the pinion 85, which pinion meshes with the gear 26 on the drum 27. By means of this train of mechanism a reciprocating motion is given to the conveyer frame 70, and as the conveyer frame moves forward in the trough the blades lift and trail over the concrete, and as it moves backward in the trough the blades dig into the concrete and carry the concrete back with it. The reciprocation of the conveyor frame 70 of about one foot is thought to be suiiicient. At suitable intervals in the bottom of the conveyor trough 62 l provide openings 90 with slides 91 closing said openings, over which the concrete can travel to the rear end of the conveyer trough.

When this mixture is used for street work, the mixer can be stationed in the middle of the street and set in operation, and as the concrete travels through the conveyer trough 62 and is discharged at its rear end, the trough can be slowly swung from one side of the street to the other, dumping the mixed material in place in the Street, and

after a circular course of concrete has thus been laid in the street, the shutter 91 nearest the end of theV conveyor trough can be opened, which will cause the concrete to be thereafter laid in a circularvcourse parallel to the course that has already been laid and nearer tothe machine. Vln this way the. conveyer trough can be swung back to the other side of the street, after which another slide can be drawn, exposing lanother opening which will cause the concrete to be deposited in another parallel circular ycourse of still smaller radius. In this, way a length of street of about twelve or fourteen feet may be laid without moving the machine. lt will beV understood ofcourse that the workmen with their shovels will spread the concrete as rapidly as it is discharged from the machine, applying it to the street in the proper thickness, but in such case it will not be necessary to use wheel barrows for the purpose of transporting the mixed concrete from the discharge end of my conveyer to the place where it is to be used on the street, as in anv case it will be deposited within easy shoveling distance of its final resting place. After this much of the street has been laid, the mixer can be advanced a suitable distance, when the slides in the conveyer will be closed and the material will again be discharged from the end of the trough, repeating the operationV as above described. A

The front end of the mixing drum 27 is provided with a casting 95 which has a plate therein extending across the opening of the cylinder and partly closing it, and has a flange thereon which envelops the edgey of the cylinder, by which it is attached to the cylinder. The opening through the plate at the end of the cylinder is indicated by dotted lines in Fig. t. The flange of the casting 95 is machined and formed of a circular track which revolves in the rollers 96, mounted to rotate on the frame on either side of the forward end of the mixing drum, and by which the mixing drum is supported. The mixing drum 27 is also provided with a collar 97 which may also preferably be formed as a casting7 which collar has its periphery machined and forms a bearing for said mixing drum, said collar engaging with and rotating in suitable rollers 98, `9S, which rollers are mounted at a suitable place in the place.

casting On the cement hopper l preferably mountV a bracket 101 on the lower end of which is a bearing 102 withy vwhich engages the shaft 4-5 which carries the worm that feeds the cement from the hopper.

I preferably mount a motor or engine on the front platform of the machine, the power generated by which is applied to the shaft which is the main driving shaft of the machine and by which all the other parts of the machine are in turn driven. I prefer to interpose some form of friction clutch between this shaft and the source of the power so that the mixer may be stopped and started without stopping the motor or gasolene engine that may be used.

The operation `of my machine is as follows The machine is stationed at any convenient place where it can discharge the concrete ready mixed at the place where it is to be used, and the machine is started in operation. rIlhe workmen are stationed on both sides of the machine, and shovel the sand into the feeding drum on one side and the crushed stone into the feeding drum on the other side, it being understood of course that the angular velocity of these drums, together with the angular velocity of the feed screw of the cement hopper, has been adjusted so as to supply to the mixing drum the material in the proper' proportions. 'Ihe menare instructed to keep the pockets of the drums full, it being understood that any material in excess of this will roll olf and drop to the ground as the drum revolves. In this way the material in the proper proportions is dumped on the chute, from which it is discharged into the mixing drum in which it is thoroughly mixed, rst dry and afterward moistened and further mixed, after which it is discharged on the conveyer trough, along which in turn it is carried to the point of discharge, the conveyer trough being swung backward and forward and the openings in the bottom thereof being uncovered for the purpose of dumping the concrete as near to the point where it is to be used as possible.

For street work I prefer to use a long conveyer trough, but for ordinary construction work a short conveyer trough will answer the purpose just as well. In such case it would be understood that the material is to be fed into wheel bai-rows and by them conveyed to the place where it is to be used. It frequently happens however that while the machine is operating continuously, ythe wheel barrows are not presented to the machine in sufficiently regular succession to take the mixed material away from the machine as rapidly as it is formed. In such case the conveyor trough can "be used as a reservoir in which the mixed concrete can be stored without being discharged therefrom -until the wheel barrow is in place under the trough, and to throw the conveyer 'mechanism of the trough out of action a clutch is provided that will permit the concrete to accumulate in the trough and provide again for the discharge of it .as soon as the wheel barrow is in position to receive it.
